Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723924, here are decompositions:

3 + 8723921 = 8723924
31 + 8723893 = 8723924
37 + 8723887 = 8723924
73 + 8723851 = 8723924
103 + 8723821 = 8723924
193 + 8723731 = 8723924
271 + 8723653 = 8723924
331 + 8723593 = 8723924

Showing the first eight; more decompositions exist.
